#160578 - CCD Reader Project Problem! |
Hi all,
I faced with a problem in my CCD Reader Project, The Project is based on reading TCD2950(TOSHIBA CCD Image SensorCCD (charge coupled device)) And Sending it's pixel value via USB to PC, I used FT245,well known usb chip from FTDI,for PC Side using FTD2XX.dll for handling usb transactions,I read each pixel in 3.3 usec or 1.65 usec.But the problem,when i send pixels every 1.65 usec 300-400 pixel lost,and when i send those every 3.3 usec 20-30 pixel are lost!! what happen?the ft245 datasheet says that the throughput is 1 MB/Sec! Is this problem based on USB Chip or PC Side Application? Thanks Mehdi |
